(GB) Mounting:
1. Fasten the DIN rail (TH 35-15 or TH 35-7.5 acc. IEC/EN 60715) as shown in Fig. I on the mounting plate, horizontal
mounting position, input terminals on bottom, respect the minimum distance to other units (see Fig. I)
2. Snap on DIN rail as shown in Fig. II
1) Tilt the unit slightly upwards and fit the unit on the DIN rail
2) Lift it downward until it hits the stop
3) Press against the bottom front side for locking
Shake the unit slightly to check the locking
3. Remove the unit from the DIN rail as shown in Fig. III. Use a screwdriver for the unlocking.
Electrical connection:
o
Input side [L, N,
]
Set the front-face „INPUT VOLTAGE SELECTOR" (CP-S 24/10.0, CP-S 24/20.0 - see Fig. I) in desired position.
Connect the input terminals L, N,
Cable cross sections, stripping length of the cable, tightening torque etc. - see technical data.
The protective earth conductor must be connected (class of protection I).
Actuate the plug connector (CP-S 24/5.0, CP-S 24/10.0) only when the power is off.
The installation must be executed acc. EN 60950, provide a suitable disconnecting device (e.g., line protection switch)
in the supply line.
Fuse protection of the input side - see technical data.
Output side [L+, L+, L-, L-]
Rate the lines for the maximum output current or provide a separate fuse protection.
Fuse protection of the output side - see technical data.
We recommend to choose the cable cross section as large as possible in order to minimize voltage drops.
Observe the polarity.
Actuate the plug connector (CP-S 24/5.0, CP-S 24/10.0) only when the power is off.
The power supplies are overload, short-circuit and no-load proof (see characteristic curve).
The secondary side of the power supplies is electrically isolated from the input and internally not earthed (SELV) and
can therefore be earthed by the user according to the needs with L+ or L- (PELV).
Operating/Function:
Operational status indication:
The green LED „OUTPUT OK" (Fig. I) is lightening during operation.
Adjustment of the output voltage:
The output voltage can be adjusted in the range of 22 to 28 V by means of the potentiometer "OUTPUT Adjust".
Parallel operation: (see Fig. IV)
In order to increase capacity and to enable redundancy, devices of the same type can be connected in parallel.
For a symmetric current distribution it is advisable to execute the line connections with the same cross sections and same
lengths.
Redundancy:
Redundant circuits are used to increase the operational reliability in case of errors (e.g., wrong wiring, blow of the fuses
in the primary circuit, failure of single devices). If a fault occurs in the first power supply circuit (called initial fault), power
to all loads is then supplied by the second, redundant supply circuit. For this reason the power supply units to be
connected in parallel must be sized in such a way that the total current requirement of all loads can be completely
covered by one power supply unit.
